### 3.5. The Interfaces Group

The definition of the ifNumber object was incorrect, as it required all interfaces to support IP. (For example, devices without IP, such as MAC-layer bridges, could not be managed if this definition was strictly followed.) The description of the ifNumber object is changed accordingly.

The ifTable object was mistaken marked as read-write, it has been (correctly) re-designated as not-accessible. In addition, several new values have been added to the ifType column in the ifTable object:

          ppp(23)
          softwareLoopback(24)
          eon(25)
          ethernet-3Mbit(26)
          nsip(27)
          slip(28)
          ultra(29)
          ds3(30)
          sip(31)
          frame-relay(32)

Finally, a new column has been added to the ifTable object:

          ifSpecific

which provides information about information specific to the media being used to realize the interface.
